0.14-dev how to know what tweens are running for an entity

[occuros]

Currently testing out the 0.14-dev release.

Before I added most of the time my tweens directly on the entity with Tracks, this now is achieved with additional entities having a TweenAnim + AnimTarget.

Now the problem I have is that not clear to me how I would query to know if there are currently any tweens running for the specific entity.

Also the TweenAnim has now no more generic parameter, so how can I find out if there is currently another Transfrom tween being used on the same entity?

Right. Note that you can skip the AnimTarget if you target a component on the same entity. Just FYI.

I don't think there's a simple way readily available. What I could suggest is:

• Organize your data, and especially your entities and components, in a way that makes it easy for you to find this if that's important. For example, spawn all TweenAnim on child entities of their target. That way you can iterate over the children.
• I wonder if there's a way we could leverage relationship here, by tagging the target entity with another component and putting it in a Relationship with the AnimTarget? Feel free to open an issue if you think that's interesting; I hadn't thought about it but that's probably a good use case for relationships. Downside is probably the extra component.

Also the TweenAnim has now no more generic parameter, so how can I find out if there is currently another Transfrom tween being used on the same entity?

Not the most user-friendly but you can do TweenAnim::tweenable().target_type_id() and compare that to TypeId::of::<Transform>().

I do think it would be a very good use case for relationships, especially as every TweenAnim targets exactly one entity, but an entity can be targeted by multiple.

Might be good to have this as a method on the TweenAnim with a generic parameter?
